Lies, computer detection and humans

Can A Computer Pick Out Fake Online Reviews When Humans Can’t? | Techdirt. 22 August 2011

It is an interesting study for several reasons. First, it seems to say that algorythms can detect some lies (the example here was fake reviews for hotels). There is no crime here, but the implications for criminal law is quite obvious. The dream of a lie detector that would allow us to know the truth (an endless pursuit) had led the US to try to analyse movements of liers and non liers, but without real success. If this software could be used or developed in other contexts, then I can see how law enforcement authorities would be tempted to use it, with all the problems of reliability and human rights it would create.

Secondly, it made me think of a software a French Uni has developed to detect the faces of real children in what can be hidden images (your eye only sees a tree, but behind is coded an other image) or distorted images (adults..). It is an algorythm that has been developed and which is more than 90% accurate and used for detecting child pornography images and paedophilias’ rings
